Šiuolaikinės organizacijos informacinėse sistemose gausu įvairių ataskaitų kurios reikalingos darbuotojams. Problema yra didelės laiko sąnaudos šių ataskaitų kūrimui ir atnaujinimui. Ji kyla iš to, kad egzistuoja funkcinė atskirtis tarp profesionalių ataskaitų dizainerių ir galinių vartotojų. Magistrinio darbo tikslas yra panaikinti funkcinę atskirtį tarp galinių vartotojų ir profesionalių ataskaitų dizainerių sukuriant internetinėje aplinkoje veikiantį įrankį ataskaitų kūrimui automatizuoti. Toks sprendimas turėtų ženkliai sutrumpinti ataskaitų kūrimo–spausdinimo ciklo trukmę. Įrankio vartotojo sąsaja bus stengiamasi kiek galima priartinti prie panašaus funkcionalumo kaip lokalių ataskaitų kūrimo įrankių. Šiame darbe yra analizuojama organizacijos aplinka ir ataskaitų kūrimo–spausdinimo ciklas, pateikiama jau sukurtų įrankių ir sprendimų analizė panašioms problemoms spręsti. Taip pat yra pateikiami išnagrinėti sistemos archietktūros variantai bei įvertintos rizikos susijusios su būsimo projekto vykdymu ir pasiūlytos priemonės rizikai mažinti. Projektinėje dalyje yra pateikiamas kuriamo įrankio projektas pagal RUP metodiką. Įrankis realizuotas naudojant AJAX technologiją prezentacijos lygmeniui ir ASP.NET platformą taikomųjų uždavinių lygmeniui. Sukurto produkto įvertinimui buvo atliktas Internetinio įrankio ataskaitų kūrimui automatizuoti efektyvumo tyrimo ekspermentas, kuris parodė, kad sukurtas įrankis nepanaikino funkcinės atskirties, bet ją sumažino.

Šiame darbe sprendžiamos grafinio vientisumo reikalavimų vaizdavimo loginiuose duomenų modeliuose bei jų kodo realizavimo problemos. Sprendžiant šiuos uždavinius, buvo analizuojami vientisumo reikalavimų tipai, UML plėtimo mechanizmai bei esamos vientisumo reikalavimų įgyvendinimo CASE įrankiuose galimybės.Vientisumo reikalavimus UML modeliuose galima užrašyti OCL kalba, tačiau OCL yra per sudėtinga daugeliui projektuotojų. Be to, SQL kodo generavimas iš OCL kol kas nėra efektyvus. Šio magistrinio darbo tikslas yra padidinti UML CASE įrankių duomenų bazių projektavimo galimybes, sukuriant vientisumo reikalavimų vaizdavimo ir kodo generavimo priemones. / Fulfillment of data integrity constraint requirements is one of main problems in information system development process. The constraints are implemented at physical system development level. Despite the fact that most of current UML CASE tools allow to specify constraints using OCL language, for the most of system analytics and architects use of OCL is too complicated. Currently SQL code generated from OCL constraint implementation is not effective. In this study we will present alternative approach for constraint requirement implementation using UML2 extension possibilities – profiles and stereotypes with tag values. Also we will present SQL code generation template language and code template based constraint requirement transformation to SQL code algorithm. It was used to extend UML Case tool MagicDraw.

Computer-aided fixture planning (CAFP) is an essential part of Computer-aided design and manufacturing (CAD/CAM) integration. Proper fixture planning can dramatically reduce the manufacturing cost, the lead-time, and labor skill requirements in product manufacturing. However, fixture planning is a highly experience-based activity. Due to the extreme diversity and complexity of manufacturing workpieces and processes, there are not many fixture planning tools available for industry applications. Moreover, existing CAFP methods rarely consider integrating fixture environmental factors into fixture planning. Automatic fixture planning using VR can provide a viable way for industries. This thesis develops automated approaches to fixture planning in a virtual environment (VE). It intends to address two important issues: automatic algorithms for fixture planning, and the VE to support high fidelity evaluation of fixture planning. The system consists of three parts including fixture assembly planning, feasibility analysis of assembly tools, and motion planning for fixture loading and unloading. The virtual fixture planning system provides the fixture designer a tool for fixture planning and evaluation. Geometrical algorithms are developed to facilitate the automatic reasoning. A Web-based VE for fixture planning is implemented. The three-dimensional (3D) model visualization enables the fixture simulation and validation effectively to investigate existing problems. Approaches to construct desktop-based large VEs are also investigated. Cell segmentation methods and dynamic loading strategies are investigated to improve the rendering performance. Case studies of virtual building navigation and product assembly simulations are conducted. The developed algorithms can successfully generate the assembly plan, validate the assembly tools, and generate moving paths for fixture design and applications. The VE is intuitive and sufficient to support fixture planning, as well as other virtual design and manufacturing tasks.

Harmonic distortion in a power system can excite non-characteristic harmonics from converter interfaced loads and generators which can then propagate back into the system, exciting other harmonics in the system. In this thesis, a harmonic analysis tool is presented that is designed to perform high accuracy, computationally efficient, steady-state harmonic analysis of distribution systems when multiple converter interfaced loads and generators exist in the system. The harmonic analysis tool requires less detail and engineering time than PSCAD/EMTDC while offering reliable assessment of harmonic coupling problems that are not captured by existing frequency-domain harmonic analysis tools. To do this, 5 harmonic models of common power electronic converter topologies were developed and implemented into this tool. The harmonic models are shown to be highly accurate; when tested in an unbalanced system with even and odd harmonic distortion, the harmonic models showed a maximum error of less than 0.4% when compared to PSCAD/EMTDC.

The aim of this thesis is to evaluate the use of Search-based Procedural Content generation (SBPCG) to help a designer create levels for different game styles. I show how SBPCG can be used for level generation in different game genres by surveying both paper and released commercial solutions. I then provide empirical data by using a Genetic Algorithm (GA) to evolve levels in two different game types, first one being a space puzzle game, and the second a platform game. Constraints from a level designer provide a base to create fitness functions for both games with success. Even though difficulties with level representation make it hard for a designer to work with this technique directly, the generated levels show that the technique has promising potential to aid level designers with their work.

The thesis raises questions concerning prehistoric conditions in a high mountain region in central Scandinavia; it focuses on the human use of stone and on hunting principally of reindeer. An analysis of how the stone material was utilized and an approach to how large mammals were hunted result in a synthesis describing one interpretation of how the vast landscape of a region in the central Scandinavian high mountains was used. With this major aim as a base questions were posed concerning the human use of stone resources and possible changes in this use. Preconditions for the occurrence of large mammals as game animals and for hunting are also highlighted. A general perspective is the long time period over which possible changes in the use of stone and hunting of big game, encompassing the Late Mesolithic, Neolithic, Bronze Age and to a certain extent the Early Iron Age. Considering the manufacture of flaked stone tools, debitage in the form of flakes from a dwelling, constitute the base where procurement and technology are essential. The occupation of the dwelling covers a period from the Late Mesolithic to the Bronze Age. Possible changes in lithic use are discussed based on an analysis of debitage which includes testing variables reflecting various steps in the process of flaked stone tool manufacture. Also, the results are discussed from a methodological aspect; the classificatory aspect of analyzing large flake assemblages is implied. The result of the flake analysis indicates differences in the use of stone from the Late Mesolithic to the Bronze Age/Early Iron Age. These differences are interpreted in a three-part chronological division and as theoretically proceeding in a manufacturing process of five steps including acquisition, reduction through three steps and use of completed tools. A pattern, dividing the Bronze Age use of stone from that of the Neolithic and Late Mesolithic is discerned and discussed in terms of changes in procurement strategies and technology. Also, social organization is touched upon. When approaching the issue of hunting the character of data differ; archaeological and palaeo-environmental data together comprise the base for a discussion of possible changes. This is based on a theoretical model applied in a hypothetical research design. Archaeological categories of remains relevant in hunting contexts together with ethnographic and traditional hunting techniques are discussed. They constitute the base and illustrate possible variables in the testing of the hypothetical model. Changes in the Holocene climate are clear, just as changes in the archaeological record are observable. Together these circumstances indicate changes in the hunting process. The structural changes in economy and society that occur in central and north Scandinavia during stone-using periods are discernible in the region studied here. / digitalisering@umu
